"It
blows my mind that you're now the age I was when we first met," the
now-25-year-old wrote on Instagram.

Rodriguez also reflected on "getting to grow up" with Ariel "for
the past 10 years," penning his sweet birthday wishes alongside a
side-by-side photo of the pair from both their early and present "Modern
Family" days.

"You are such a kind, talented, and beautiful woman,"
the actor wrote of Ariel. "Cheers to many more birthdays together!"

Eric Stonestreet offered his thoughtful words to the "sweet,
adorable and wildly talented" birthday girl on Twitter, and reminded her
that he's not the only one who has her back.

"My promise to have Ed O'Neil crush anyone who hurts you
remains," he joked.

Although Ariel has only just been crowned an official adult, she recently said
that child stardom may have helped her get prepared early.

"I've kind of been in adulthood for a little while now,"
the actress, who became an emancipated minor in 2015, told People.

Adding, "I love what I do, but I don't know
if it's a choice I would have made on my own. People criticize you at an
extremely young age. There's a lot of rejection. I heard 'no' thousands of
times. That was hard to cope with."
